One simple way to do it,on ANY car that has a distributor,is to remove the distribitor from the engine,marking it before you do so that it goes back with rotor & body in EXACTLY the same position.Leave all wiring connected to the distributor except the High Tension(HT) lead & connect a jumper lead from the distributor body to a good ground on the engine.Then go inside the car & turn on the ignition but DO NOT crank the engine.Let the disconnected end of the HT rest on its boot against the car body & holding the distributor in one hand,spin the distributor drive shaft with the other hand.You should see showers of sparks on the end of HT lead as the shaft is spun indicating that the ignition module is OK.....no sparks,module's bad!

an ignition control module is simply another comuter within a car used send ignition to a cars spark plugs. All modules need a basic power source from the battery and proper ground. Ensure there is at least 12 volts to one of the pins to the module, better yet pull up a diagram and see which pin receives battery voltage and check for it there, if there is no power chances are there is a blown fuse. you must also ensure you are getting signals from cam and crankshaft sensore to the module, this is best done with an osciloscope or scan tool. If power, ground, signals and circuit integrity are acceptable and still no spark is present out from any spark plug wires when the motor is cranked chances are the module itself is bad (most likely output driver - transistor bad internally)

The ignition module or ICM is an amplifier, it takes the +5 to 0 volt low current pulses from the PCM and amplifies the voltage and current. It then feeds the amplified signals to the coil.

If a 01 sportster is getting no spark is it the voltage regulator.Has a new battery and plugs?

The voltage regulator is part of the charging system. u have a problem with ur ignition system If u have a no spark condition then check the following; Plug wires,Coils, Wiring from ignition module to coils,wiring from the main switch to the ignition module and the wiring to the trigger sensors u have a new batt just make sure it has a full charge with electronic ignitions never crank the engine over w/o grounding at least one of ur plug wires otherwise u can damage the ignition module
